使用Volley的发布方法不起作用 [英] Post Method using Volley not working
问题描述
我正在使用Volley作为我的登录页面.我需要像这样传递数据
Hi i am using Volley for my login page. I need to pass data like this manner
{
userID : '-988682425884628921',
email :'aditya@vyas.com',
passwd : '123ss'
}
我正在使用POST方法发送数据，我已经在DHC中签入，Api在DHC中工作正常，并且我正在 JSON响应，但是当我尝试使用Volley时，我无法获得响应.甚至在我的logcat中也没有任何错误.
I am using POST Method to send data,I already check in DHC, The Api is working fine in DHC and I am getting JSON Response, But when i try with Volley i am not able to get response. and not even any error in my logcat.
JAVA代码
RequestQueue mVolleyQueue = Volley.newRequestQueue(this);
CustomRequest req = new CustomRequest(Request.Method.POST,url,null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.v("tag","login response " + response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.v("tag","login error response " + error.getMessage());
}
}){
@Override
public Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("userID", "-988682425884628921");
params.put("email", "aditya@vyas.com");
params.put("passwd", "123ss");
return params;
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
mVolleyQueue.add(req);

推荐答案
解决了您的问题.刚使用过JsonArrayRequest并以JsonObject形式传递参数:
Solved your problem. Just used JsonArrayRequest and passed parameters in JsonObject form:
Map<String, String> params = new HashMap<String, String>();
params.put("userID", "userid");
params.put("email","email");
params.put("passwd", "password");
JsonArrayRequest request = new JsonArrayRequest(Request.Method.POST, "url", new JSONObject(params),
new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
System.out.println("response -->> " + response.toString());
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
System.out.println("change Pass response -->> " + error.toString());
}
});
request.setRetryPolicy(new
DefaultRetryPolicy(60000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
Volley.newRequestQueue(activity).add(request);
无需覆盖getParams()或getHeaders().
No need of overriding getParams() or getHeaders().
问题:1
您得到响应码500 ，因为服务器接受params作为JsonObject，并且我们正在尝试提供String.
Problem : 1
You were getting response code 500 because the server was accepting the params as JsonObject and we are trying to feed String.
问题:2
您正在使用JsonObjectRequet，但是服务器的响应位于JsonArray中，因此您需要使用JsonArrayRequest接受JsonArray
Problem : 2
You were using JsonObjectRequet but the response from the server was in JsonArray so you need to use JsonArrayRequest to accept the response in JsonArray
尝试让我知道这对您有帮助或不帮助:)
Try and let me know this helps or not :)
